入したトランクオープナに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic trunk lid opener in which a cancel switch, which is operated using a key cylinder of a trunk lid lock, is inserted in the electric circuit of the electromagnetic trunk lid opener, in addition to an open switch.

ランクルームの防盗性が完全ではなかった。Conventional electromagnetic trunk lid openers use an electromagnetic drive device such as a solenoid or motor that is connected to a power supply via an open switch installed at a suitable location in a single compartment to unlock the trunk lid and the vehicle body. Although the trunk lid can be opened simply by operating it, the trunk compartment was not completely burglar-proof.

る欠点を有する。Therefore, have there been proposals for a method in which a cancel switch is inserted into the electrical circuit from the power supply to the electromagnetic drive device inside the glove box, or a method in which the cancel switch is activated by rotation of the key cylinder of the glove box lid lock in the locking direction? In either method, after getting out of the car, opening the trunk and putting things in or taking things out, if you decide to cancel the trunk opener function to prevent theft, return to the car and open the switch inside the glove box lid. Alternatively, there is the inconvenience of having to operate the glove box key cylinder, and the latter has the disadvantage that the glove box must always have a lid with a lock, making it expensive.

It has a structure that cannot be unlocked.

以下図面を参照して本考案の一実施例を説明する。An embodiment of the present invention will be described below with reference to the drawings.

ト２が開くのを防止している。In FIGS. 1 and 2, L is a lock unit provided on the vehicle body side, and includes a launch 4 and a latch 4 that engage and disengage from the striker 3 when the trunk lid 2 is opened and closed on the pace plate 1.
The locking levers 5, which engage and disengage from each other, are pressed by pivots 6 and 7, respectively, while being biased by springs (not shown), and when the trunk lint is closed, the striker 3 and the latch 4 are engaged, and the locking lever 5 is engaged with the latch 4. This prevents the trunk lint 2 from opening.

き得る状態となっている。The key cylinder 8, which is also provided on the vehicle body side (trunk), is provided with a cylinder lever 10 that rotates together with the rotating shaft 9 of the key cylinder 8. When turned counterclockwise, the locking lever 5 similarly moves counterclockwise to engage or disengage the latch 4, which causes the latch 4 to spring up in the counterclockwise direction and engage the striker 3. is released, the lock is released, and the trunk lint 2 is in a so-called unlocked state in which the trunk lint 2 can be opened.

れるようになっている。On the other hand, a connecting rod 1 is connected to one end of the locking lever 5.
One end of the connecting rod 11 is engaged, and the other end of this connecting rod 11 is connected to one end of a swinging lever 13 whose center is pivoted. When the plunger 14a of the device 14 is connected and the electromagnetic drive device 14 is activated, the swinging lever 13 swings clockwise and the locking lever 5 is rotated counterclockwise, thereby causing the locking lever 5 to rotate in the counterclockwise direction. The same unlocked state can be obtained.

ープンスイッチ１５を介して電源１６に接続している。Further, this electromagnetic drive device 14 is connected to a power source 16 via an open switch 15 provided at a suitable location inside the device.

もってオープンスイッチ１５を閉じたとき前記電磁駆動
装置１４が駆動するようになっている。When the open switch 15 is closed, the electromagnetic drive device 14 is driven.

以上は既知の手動解錠機能を併せ持つ電磁式トランクリ
ッドオープナの一般的構造である。The above is a general structure of an electromagnetic trunk lid opener that also has a known manual unlocking function.

オープンスイッチ１５と直列に接続する。According to the present invention, in such a structure, the key cylinder 8 on the vehicle body side opens and closes in conjunction with the rocking of the cylinder lever 10, and the direction opposite to the key rotation direction when unlocking the trunk lid 2 with the key (clockwise in the figure). The normally closed cancel switch 17, which opens when the cylinder lever 10 contacts the movable contact piece 17a when the key is rotated by a predetermined angle in the direction of Connect in series with switch 15.

る。Since the trunk lid opener of the present invention has the above-mentioned configuration, if the intention arises to cancel the trunk opener operation to prevent theft after getting out of the car and opening the trunk to take things in and out, If you turn the key in the opposite direction to the unlocking direction of trunk lint 2,
At the dotted line position rotated by a predetermined angle, the cylinder lever 10 contacts the movable contact piece 17a and opens the cancel switch 17.

従って以降はたとえばオープンスイッチ１５を閉成して
も電磁駆動装置１４には通電されないので、該電磁駆動
装置１４は作動せず、ロッキングレバー５を回動させる
ことがない。Therefore, from then on, for example, even if the open switch 15 is closed, the electromagnetic drive device 14 is not energized, so the electromagnetic drive device 14 is not operated and the locking lever 5 is not rotated.

このためトランクリッド２は車室内からのオープンスイ
ッチ１５の操作は絶対に開くことがない。Therefore, the trunk lid 2 will never be opened by operating the open switch 15 from inside the vehicle.

なお、キーはこの状態で引く抜くものである。Note that the key should be pulled out in this state.

次に帰車してキャンセルスイッチ１７を閉成したい場合
には、キーを再び挿入して元の中立位置に戻した状態で
抜けば、可動接片１７ａが復帰して上記目的が果せるも
のである。Next, when you return home and want to close the cancel switch 17, insert the key again and return it to the original neutral position, then pull it out, and the movable contact piece 17a will return to its original position, achieving the above purpose. .

供できる等の利点がある。As described above, according to the trunk lid opener of the present invention, the key cylinder of the trunk lid lock mechanism is used to operate the cancel switch, so even if the intention to cancel occurs in the trunk of the car, Not only is it very convenient to be able to cancel on the spot without having to go back into the room, but because you can use an existing device to operate the cancel switch, it is cheaper than the locking lid of a conventional glove box. There are advantages such as being able to provide
